Possible Causes
Failed internal power supply on main PCB, loose mains connection, damaged power cord, surge-damaged control board
How to Fix / Troubleshooting
Safety: Always unplug the unit before inspecting the power cord or control board. Do not work on live circuits.
Steps to address F9:
- Check outlet and supply: Verify the wall outlet has correct voltage using a plug-in tester or multimeter. Avoid using extension cords or power strips.
- Inspect power cord: Examine the cord for cuts, kinks, or burn marks. Replace the cord set if damaged.
- Verify internal connections: Remove the rear service panel and locate the main control board. Ensure the mains input connector is fully seated and that any inline fuses are intact.
- Look for board damage: Inspect the PCB for burnt components, bulging capacitors, or scorch marks. Evidence of surge damage usually requires board replacement.
- Replace main PCB if necessary: If the power supply section is faulty (no low-voltage output to fans, lights, or UI) and fuses are good, replace the main control board with the correct Fisher & Paykel part.
